Abstract: A dynamic betting valuator system, method and computer program product which enables bettors to make, withdraw, and increase/decrease the stake of bets on the outcome of particular events at any time is disclosed. Specialized stock and stock pricing mechanisms are applied in a betting context to create the dynamic betting valuator. The systems, methods and computer program product treat the placing of a bet by a bettor as a purchase of shares in that particular outcome for the particular event. Each potential outcome for a given event has an associated “outcome stock” in which players are buying shares. Each bet amount on a certain outcome is converted into a number of shares of that outcome stock. A bettor may change his bet, i.e. have the computer program product sell shares in a particular outcome stock, prior to the event taking place, potentially making a profit from the bet despite the outcome not yet having been determined.
